Celtic Wheel of Life

I'm intrigued by the Celtic Wheel of Life  but know very little about it. So its my homework for this year!
If anyone can contribute anything useful - and I don't mean scoffing about it being for witches and pagans - please do so. I'm looking at it with an open mind and hope you can too!

The end of January/beginning of February is called Imbolc and it marks the midpoint between the Winter Solstice and the Spring Equinox. When we welcome a return to the light, lambs are born, spring flowers are emerging. Snowdrops are brought into the house. Candles are burnt and bonfires lit. 
It's also St Brigid's day when crosses are woven from rushes in Ireland and ? Scotland so Imbolc is paired with the Christian calendar.

Its also Candlemas - from the Christian calendar https://www.timeanddate.com/holidays/common/candlemas
.......and there's a Full Moon - the Snow Moon tonight.
Snowdrops are known as Candlemas Bells. 

So many traditions and beliefs coming together. 
I'm going to celebrate Imbolc in my own little way . I'll pick some snowdrops and light a candle. Tonight I'll look for the Snow Moon.

Sorry about the rambling. Just trying to understand it all!
